| 摘 要： | 传统方法制备的聚苯胺防腐蚀导电涂层,聚苯胺易下沉,使涂层电导率差.为此,借用原位聚合方法制备了聚苯胺/环氧树脂(PANI/EP)复合防腐蚀涂层.利用相应的性能测试方法检测和比较了不同反应条件下(如苯胺单体用量、引发剂的用量、酸量、聚合时间)合成的聚苯胺复合涂层的导电性能,并将其与传统方法制备的涂层进行了比较.结果表明:降低了氧化剂、酸的用量;因为降低了聚苯胺的粒径而减轻了聚苯胺粒子在涂层中的下沉,从而提高了涂层的导电性能,电导率达到1.6×10-2S/m.

| Abstract: | Composite conductive and anticorrosive polyaniline/epoxy resin(PANI/EP)coatings were prepared by using in-situ polymerization method.The electric conducting behavior of the composite coatings ob-tained at various reaction conditions(dosage of PANI monomer,initiator,and acid,and polymerization time)was compared with that of conventional same coating.It was found that the dosage of oxidant and acid for in-situ polymerization of PANI/EP could be reduced as compared with conventional methods.At the same time,th... |
